Today I brewed my own version of Russian Caravan (for those who don't know Russian Caravan is a smokey black tea known as such it seems because at some point a caravan that was carrying black tea from China to Russia got the tea smoked without them intending that and they saw it was good).
The mixture I used is based on three varieties of Chinese tea:
Pu Erh (fermented black tea)
Keemun Congou (has a slightly plumy taste)
and
Lapsang Souchong (that's a taiwanese smokey black tea, it's smoked because it's made of the bigger leafs (the smaller leafs are said to be better quality)).
I started with mixing around half Pu Erh with Keemun and Lapsang Souchong in roughly equal proportions.
